Did you ever look at the FileWriter and FileOutputStream APIs? Especially at the constructors?

Have a look at RandomAccesFile class documentation, in particular at writeBytes, seek and getFilePointer methods!you should be able to add a line at the end of the file, without reading and writing the whole file!

Wow. Just the right methods to append some lines of text to a file.

Thank you, it worked out really easy with FileWriter

public static void insertLineToFile (String line, String filename)

{

FileWriter fr = null;

try {

fr = new FileWriter(filename, true);

fr.write(line + "\n");

fr.close();

} catch (IOException e) {

e.printStackTrace();

}
